Title: Wet type chemical removing method for semiconductor crystal surface contamination
Inventor: ARUFUREETO REHINAA
IPC: C23G1/00
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To reduce expense without changing cleaning quality by a method, wherein deionized water of high purity which is added to a metal complex formation at ppm concentration is used as a wet-type chemical cleaning medium. SOLUTION: A very small amount of deionized water of high purity is used in a cleaning process, which can be manufactured as a quantitatively suitable cleaning medium while scarcely incurring expenses. As deionized water attains markedly higher purity than those of chemicals of supreme purity, cleaning operations are also improved. As an amount of metal complex formation (and a substance which reduce surface tension or an amount of ozone) is only in the range of ppm concentration, the impurity concentration is very slight and therefore goods on the market can be used ordinarily. Thereby, expenses can be reduced without changing the quality of cleaning.

Title: Desalination treatment system
Inventor: SHIOZAWA YOSHIHIRO
IPC: F22D11/00
Filed: 1989-09-29
Abstract: PURPOSE:To maintain proper performance of the condensate desalination device all the time by controlling valve means so as to close a first pipe passage and open a second pipe passage when the temperature of the inlet water of a desalination device that is measured by a temperature sensor rises above a specified value. CONSTITUTION:A temperature sensor 41 detects the temperature of the water at the inlet of a condensate desalination device which is a mixture of the condensate and the drain from a supply water heater, and the detected temperatures are sent to a temperature switch 42. The temperature switch 42 operates when the temperature detected by the temperature sensor 41 reaches the maximum temperature of use for resin, for example 60 deg.C, and it outputs the signal of opening to a supply valve 32 and signal of closing to a supply valve 29. With the supply valve 32 open and the supply valve 29 closed, the drain of the supply water heater is recovered on the side of the outlet of a condensate desalination device 15. With high temperature of the water at the inlet of the condensate desalination device the recovery point of the drain of the supply water heater is switched from the inlet of the condensate desalination device to its outlet, and by limiting the treatment in the condensate desalination device only to the condensate, it can be prevented that the inlet water temperature of the condensate desalination device exceeds the maximum temperature of use for resin and the lowering of the performance and the decomposition of the resin in the condensate desalination device are prevented.

IPC: H01L21/22
Filed: 1989-09-29
Abstract: PURPOSE:To stabilize the temperature in the semiconductor substrate mounted region in a furnace core tube by a method wherein the specific part apt to be subjected to notable temperature fluctuation and the other part in a heat treatment device are individually temperature-controlled by different heaters. CONSTITUTION:A specific heater 9 heat-insulated from another heater by a heat insulation material is provided on the peripheral part of a furnace core tube 6. Then, this specific heater 9 and the other heater are individually temperature-controlled by a controller. Accordingly, even if a part provided with a reactive gas leading-in means 7 in the furnace core tube 6 is subjected to a rapid temperature fluctuation, the temperature only of the part provided with the specific heater 9 can be compensated to be controlled by this specific heater 9. Furthermore, the mutual interference effect between these heaters will not be exercised on the temperature control by the other heater. Through these procedures, the temperature fluctuation in the semiconductor substrate mounted region in the furnace core tube can be avoided.
